Is Humminbird replacing their 800 & 900 series with the Helix?

Their web site now shows the Helix 5, Helix 7, Helix 9, Helix 10, and Helix 12 series but not the 800and 900 series (and some of the other higher end models). It looks like the new Helix 9, 10, and 12 have some really good features. I have the 859ci HD DI and the Helix 5 DI GPS and they are great fish finders. The stores are still selling the “soon to be discontinued?” models but not the new Helix 9, 10, or 12 yet. The only other high end models still listed on their web site is the ONIX series, which far exceed my price range and need.
